Chemistry 1A/1E Diagnostic exam

Chem 1A/1E: All students who want to register for chem 1A or 1E must pass the chemistry diagnostic exam before registering for the class. The exam will not be offered after the semester begins. NO EXCEPTIONS!

Chem 4: Chem 4 is designed for students who do not pass the Chemistry Diagnostic Exam with a score of 35 or higher. All students planning to register for Chem 4 are strongly encouraged to take the Chemistry Diagnostic Exam before instruction begins to accurately determine their need for the class. 

  • The test can only be taken once per registration cycle and your score is good for 2 semesters.
  • If you want to try and get a better score on the exam you must wait until the next semester to take it again.
  • If it has been longer than two semesters since you took the exam you must re-take it.
  • Scores will show in your My Sac State Student Center Test Score Summary after you take the exam.
